Abstract

An automatic toothbrush (100) comprising: a body (102) having opposite ends, a cavity (105) between the opposite ends, and at one of the opposite ends an opening (107); an output shaft (120) having a first end and a second end (124, 122), the output shaft (120) extending through the opening so that the second end (122) is outside the cavity, the output shaft having a plurality of bends (139, 141, 143, 145) between the second end and the opening; and an oral cleaning implement (104) configured to be press-fit to the shaft with the plurality of bends part of the department.

Description

[0001] related application [0002] This application claims the benefit of, or priority to, and describes the relationship between, the applications in which this application claims priority to US Provisional Patent Application Serial No. 62 / 020,072, filed July 2, 2014. technical field [0003] The present system relates to an automatic (eg, electric) toothbrush, and more particularly, to an automatic toothbrush having a one-piece offset output shaft and a method of making the same. Background technique [0004] Oral hygiene is an important element in personal care. Conventional automatic toothbrushes can have rotating and / or vibrating oral cleaning implements, such as brush heads, to effectively clean teeth and remove plaque. The oral cleaning implement is attached to and driven by the output shaft of the automatic toothbrush, which is usually formed from a plurality of assembled elements, some of which are machined. For example, the outer portions of these output shafts...
